It is easy to modify the standard carrier in the TDC 716 
if you have access to a milling machine. Use some mounts 
to mark exactly how large the openings will need to be, 
with a little margin, but not too much, or the dowser won't 
close completely.  I mounted the entire carrier, with the 
dowser open in the vise, and milled the openings to the 
correct width, finishing the corners with a small round 
file, as I didn't have a small enough mill for the corner 
radius.  You might be able to do the same thing freehand 
with a Dremel, but it would be slow going.  If you wanted 
to use a nibbler, you would probably need to disassemble 
the carrier.  

The Selectron carrier is much more difficult, as it 
requires modification to the dowser.  I haven't tried it 
yet.

I did try enlarging the openings on a Nord projector, but 
was unsuccessful, as the Nord's condensers are not large 
enough to provide coverage of 7 perf.
